` `Be' it known that I, HARiz'Y' L. M'I'LLNni, a citizen of the United States', residing at Morgantoin'in the county of Burke, State 0f North Ca'iolina, have ilvelirledertai new and useful Improvements in Gas=Pro ducers, of which the following is a description, reference being had tthe accompanying drawing andtothe ligures of reference markedthereon.

-My invention relates to improvements in gas i producers and particularly to grates therefor. A

The object ef my invention ie te prende an apparatus of this character, in which tarry caking fuels, well as saw-dust, spent tan bark, peat 'and the like, having a high percentage of moisture, may be readily handled and perfectly gasifed, preventing the lformation of chimneys throigli the fuel bed; Such a formation woif chimneys through the fuel bed results in an uneven action of the air blasts and greatly impairs the quality of the gas produced. The present invention wholly eliminates this objection.

Another object of my invention is to provide a machine in which the fuel niass is thoroughly stirred, breaking up the arches, cake'sand chimneys and thus makes the continuous operation of the produce possible.

A still further objectof my invention is to provide a simple, cheap and effective striicture ,to accomplish the foregoing objects, Which has Certain 4details of 'Stiictilie and combinationoi' parts hereinafter more fully set forth.

In the accompanying drawings Figure 1 is a vertiealtransverse sectional View of a gas Yproducer provided with my invention;

'the shoulder 9 forming known form andtherefore needs no further description. The lower end of the fire pot 2 below the fire brick 3 is provided with a number of angle iron' brackets 4 bolted or'otherwise rigidly secured to the shell 5 and arranged with the horizontal portion 6 1n position shown in Fig. 1A of the drawings. The angle iron brackets 4 are provided on the under face of the horizontal portion, with the webs 7 forming means by which the stationary grate is' supported as will be hereinafter more fully described. Carried by the base upon which the pro dueer is supported is a' central standard 8 having `its' upper` end 8 reduced forming a support for the stationary gratel() as shown in Fig. 1 of the drawings; 1

The stationary gratelO is as shown in Fig; 4 of the drawings, formed of siX sections 11, V shaped in plan view having their inner ends curved to fit against the reduced portion 8 of the standard and resting upon theshoulder 9. The outer edges of the sectiene are curved toforrn a'circular grate as fully shown in Fig.V 4 of the drawings and the saine beingof a diameter considerably less than the interior diameter of the shell 5 as shown in Fig. 1 of the drawings. Each section is composed of the outer flange 12 entirely surrounding the same and carrying the V shaped grate bars 18 arrangedtangentially to the anis of the grate. The outer edge of each grate section is provided with two oiitwar'dly extending parallelarms 14 and 15 bolted to the webs 7 of the brackets 4 by means of bolts 16' whereby the same is rigidly supported in the lower end of lthe poduceri The upper face `of the angle iron brackets 4 `has bolted thereto the upwardly'eXtending arIns 16',- `their upper ends provided with rollers 17, upon which the rotary basket 18 rests and is free to rotate, as will be later described.

The rotary basket 18 is of a circular basket like ferm, having a flange 19 entirely sri'oundiiigjthe saine and resting upon the rollers 17; The bottom of the basket is provided with an opening 20y of a size consider-` ably less than `the top ofthe basket and y Patented Aug. 5, 1919. i Application tied sett-enter 9, 191s.

portion `of the standard and thereby the basket is maintained in position in its rotation, as will be readily understood. `The sections of the rotary basket are formed with flanges 24, through which bolts pass and by means of which 'grate bars 25 are supported. The abutting z faces of the .flanges are cut away, as indicated at 26,

forming air passages27 to Vallow the upward passage of airk to cool theflanges and prevent warping thereof. The outer lower edge of the flange of the basket is provided with teeth 28 forming algear, with which meshes the pinion 29 and which is rotated in any desired manner and by means" of which the basket is rotated, aswill be readily understood. v

The stationary grate, as shown, is of a size to at all times cover the opening in the' rotary basket, so that the sawdust or other gas producing fuel is prevented from passing from the grate through said openinO. The fuel, as is understood, rests in the basket-like grate and above it, and upon the rotation of the basket the fuel is grasped thereby and twisted upon itself, and at the same time every portion is progressively subjected to anv upwardly heaving motion, due to the unequal length and slope of the basket sides as they travel around inthe rotation thereto. kAs the ash works down tothe opening in the bottom, it is dragged across the grate bars of the stationary grate and forced therethrough to the ash pit, thus doing away with the necessity of raking. This operation on the fuel absolutely prevents the same arching across above the grate to form cavities in the form `of chimneys and `thus a more uniform and better gas is produced.

It will be understood that I do not Ywish to be limited to the exact construction of the basket like grate shown and which has the motion imparted to it to give the combined twisting, heaving and scraping motions to the fuel bed, but it will be obvious that other arrangements maybe devised for carrying out this object.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A gas producer comprising a furnace, a stationary'grate and a rotary basket like grate having an opening directly above the stationary grate, said rotary basket like grate having sides of unequal `slope and length, whereby the movement of said basket like grate causes an upward heaving motion of the fuel above and the ash is dragged across the grate bars ofthe stationary grate. 2. A gas producer, comprising a furnace, a stationary grate, a rotary basket like grate having an opening in its bottom eccentrically arranged forming sides of unequal slope and length and adapted to cause an upward heaving motion of the fuel above.

3, A gas producer, comprising a furnace,

" stationary grate, a. rotary basket like grate having an .opening in its bottom eccentrically arranged and'` forming sides of ununequal slope and length and adapted to cause an upward heaving motion of the fuel above,- andjmeans for rotatably supporting the rotarv grate adjacentits upper end and allowing the lower edge to freely move upon the stationary grate. l

5. A gas producer, comprising a furnace, a stationary grate, a standard supporting the center of the said grate, a rotary basket like grate having an opening in its bottom eccentrically arranged and forming sides of unequal slope and length and adapted to cause an upward heaving motion of the fuelV above, an ear extending into said opening and havingvan opening receiving the standard for centrally supporting the grate, and means for rotatably supporting the upper end of the rotary grate.
